CAN" OPENER.

Application filed. April 29, 1922. Serial No. 557,334.

T 0 all whom it may concern:

Be it known that we, Jnssn S. MOORE and .Tnaoarn MEYER, citizens of theUnited States, and residents of New York, county and State of New York,have invented certain new and useful Improvements in Can Openers, ofwhich the following is a specification.

This invention relates to a type of can opener in which acircular orsemi-circular opening is out into the top of the can by a singleoperative movement of the device. The object of the invention is toprovide a can opener having such characteristic and of such simplicitythat it may be manufactured at very small cost, while at the same timeit may be positive in its action.

The invention will be understood by reference to the accompanyingdrawings, in which- Fig. 1 comprises a side elevation of the device, and

Fig. 2 is a plan view of the same.

Fig. 3 is an end elevation of the can opener.

Fig. 4; is a perspective view of the device, illustrating the manner inwhich the top" and side of the can is penetrated by the curved prong,thus affording the latter two fulcrum points.

By reference to the drawings, it will be seen that the device consistsof an arm or hand lever B formed at its outer end with the downwardlycurved prong A which is adapted to penetrate the top and side of thecan, as shown in Fig. 4e. Overhanging prong A is a fulcrum-blade A", toadapt the device for use as an ordinary can opener. In such case theprong A serves as the knife.

The hand lever B is provided, immediately in advance of prong A, with ablade D which may be circular but which in the present instance issemi-circular. It will be noted from the drawing that the blade D has adepth gradually increasing toward the centre from each end and merginginto a point C, the rear of the blade being disposed nearest the prongA.

At opposite sides the blade is formed with an angular slot so that twosmall wedge-like sections E of the blade may be bent inwardly for thepurpose hereinafter described.

In opening a can with the device, the operator pierces the top and sidewall of the can with the prong A so that the pierced walls of the canmay act as a fulcrum-bearing for the hand lever. The lever may now bedepressed, point C entering the can fol lowed gradually by the entirecutting edge of the blade.

Prior to the end of the cutting movement of the blade wedge-hooks E willbe carried below the top of the can. However the edge of the cut-outsection, temporarily displaced by the wedge-hooks will spring back overthe horizontal top walls of the latter. And in the reverse movement ofthe device the cut-out section of the can will be elevated thereby.

It will be understood that various changes in the embodiment of theinvention shown in the drawings may be made without departing from thespirit of our invention. The blade may be cast in one with the handlever, or it may be formed separately and welded or otherwise secured tothe lever. And if desired the hand lever may be permanently attached tothe frame. However, the means of attachment shown and described isdesirable in that the members may be very readily assembled anddisassembled for packing or for cleaning after use.

What we claim and desire to secure by Letters Patent is A can openercomprising a lever arm having at its front end a forwardly projectingcurved prong adapted to penetrate the top and side wall of a can toprovide two spaced fulcrum points, a fulcrum-blade overhanging saidprong, and a curvilinear blade carried by the lever arm, as and for thepurpose described.

In testimony whereof, we have signed our names to this specification inthe presence of two subscribing witnesses.
